Application filed February 3, 1905. Serial No. 243,967.

To (r/Z7, 1071/0712, it may concern:

lie itknown that I, James J. Pmvnas, a citizen of the United States, anda resident of (lentralpark, in the county of Nassau and State of NewYork, have invented a new and Improved Water-Elevator, of which thefollowing is a full, clear, and exact description.

This invention relates to improvements in apparatus for elevating waterfrom wells, the object being to provide a water-elevator of simple andnovel construction and in which the water is forced to the point ofdischarge by ail-pressure.

Other objects of the invention will appear in the general description.

ll will describe a water-elevator embodying my invention and then pointout the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in both the figures.

Figure l is a sectional elevation of a waterelevator embodying myinvention, and Fig. 2 is a sectional elevation showing on a larger scalethe receiving-cylinder and valve mechanism.

The water-elevator comprises a cylinder 1, designed to be wholly orpartly submerged in the water of a well. This cylinder is closed at thetop and bottom, and arranged in the bottom wall is aninlct-chamber2,]1aving ports 3, through which water passes into thecylinder upon the opening of a valve 4:, mounted to move vertically in avalve-casing 5, which, as clearly indicated in Fig. 2, is formed in twosections having screw-thread en agement one with the other. Thevalve-casing is provided with a beveled seat 6 for the valve, andextended. downwardly from the valve are web portions or wings 7, whichform the lower guides. These Web portions at the lower end are connectedto a disk 8, provided with ports 9. The valveis further guided by itsstem 10, extended. loosely through a perforation in a ported spider 11,formed in the upper section of the valve-casing. The valve-casing isalso provided above and below the spider 11 with inlet-ports 12.

it will be noted that the outer surface of the valve-casing 5 istapered, and the opening in the part 2 for receiving said taperedportion is correspondingly shaped and ground. By this construction atight fit is formed between the casing and. receiving-chamber 2, and theparts will be held in such close connection by the weight or gravity ofthe valve-casing and the discharge-pipe 13, connecting therewith.

The discharge-pipe 13 leads upward through a valvelcss air-pressure pipelet, and, if desired, a guide or guides 15 may be secured to thedischarge-pipe 13 and engaged with the interior of the air-pipe. Theair-pipe 1 1 is closed at the top, and communicating therewith through apipe 16 is an air-pressure pump 17. The pipe 16 is provided with a valve18, and the discharge-pipe 13 has above the pipe l t a discharge-cock19. From the pipe 13 a supplemental discharge-pipe 20 is shown, and itmay lead into the basement of a house or to any desired point, and inthis pipe 20 is a valve 21. An auxiliary air-pressure pipe 22,

leading from the house and connecting with a Y suitable source, connectswith the main airpipe 14..

In the operation air is forced into the cylinder 1 by means of the pumpwhile the cook 19 and valve 21 are closed, it being understood thatprior to this the water in the well will open the valve t and pass intothe cylinder 1, partly if not completely filling the same, when thevalve closes by gravity. The air-pressure will hold the valve closed andforce the water up through the pipe 13, to be discharged through thecook 19 or through the pipe 20 when the valve 21 is open.

It will be noted that the air-pipe 1 1 is suiiiciently large to permitthe pipe 13, carrying the valve-casing, to be drawn upward therethroughwhen it is desired to repair the valve or valve-casing, and this removalof the valve and valve-casing does not in any way disturb the locationof the cylinder 1.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. In a water-elevator, a cylinder adapted to besubmerged, a ported receiving-chamber arranged in the lower wall of saidcylinder and having a tapered opening, a valve-easing having a taperedportion for engaging in said opening, a valve in the valve-casing, thesaid casing being provided with ports, a dischargepipe leading upwardfrom the valve-casing, the said valve-casing with its tapered portionand the said discharge-pipe, forming a practically continuous structurewhereby the said parts may be passed through the air pipe withoutdisturbing the cylinder, an air-pipe surrounding the discharge-pipe, andan airpump communicating with said air-pipe.

2. A water-elevator comprisingacylinder, a receiving-chamber arranged inthe lower Wall thereof, a valvecasing removably engaging in said chamberand provided with ports, a valve in said casing, adischarge-pipeconnected to and leading upward from the valve casing, a valvelessair-pipe through which the discharge-pipe passes, a pump havingcommunication with the air-pipe, and a discharge-controlling valve atthe upper portion of the discharge-pipe.

8. A water-elevator comprising a cylinder closed at the top and bottom,a valveless airpipe leading into the upper end of said cylinder, anair-pressure pump having connection with said pipe, a receiving-chamberengaging with the lower wall of said cylinder and having inlet-ports, avalve-casing for removably engaging in said chamber and having ports, anupwardly-opening valve in the valve-casing, a pipe connected to andleading upward from the casing through the air-pipe, an auxiliarydischarge-pipe leading from the first-named discharge-pipe, a valve insaid auxiliary discharge-pipe, and an auxiliary airpressure pipe leadinginto the main air-pipe.

In testimony whereof I. have signed my name to this specification in thepresence of-two subscribing witnesses.

JAMES J. POWVERS.
